BARs (Barometric pressure) is the amount of force that your espresso machine exerts on the grounds of your coffee while delivering high-pressure water. Your espresso machine is pushing hot water through the grounds of coffee at nine times the current atmospheric pressure.
The pressure of your espresso machine is important because it allows water to move through the grounds of your coffee with the right speed and with the right intensity. If the pressure isn't high enough, the oils and flavors will not be extracted correctly. On the other side, if the pressure is too high the water will be pushed through the coffee grounds too quickly, and you'll end up with a weak, over-extracted cup of espresso.
You can control the pressure of your espresso maker by changing the screw on the espresso pump. Commercial machines as well as some high-end home machines have pumps with rotary that can be adjusted. However, for the less expensive home machines that have the vibrating pump, altering the pressure is not possible without getting into DIY hacks. However, companies like Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure in the portafilter during the brewing process.
Temperature
Temperature is one of the most important elements in a great espresso shot. If the water is too hot, it will cause the coffee grounds to burn and create a bitter coffee. The ideal temperature for extraction is about 200 degrees Fahrenheit, which allows the water to extract all the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machines have the thermoblock, also known as a thermocoil that heats water and maintains it at a constant temperature throughout the extraction process.

Grind
A barista here espresso machine must also provide a variety grind settings for you to have the most control over the final cup of coffee. Some machines include an analog pressure gauge, that looks cool and can help you learn about your brewing skills.

Another excellent feature of this machine is its built-in burr grinder. This feature is ideal for beginners because it eliminates the need for an additional grinder. The grinder is an stainless steel conical unit with 18 settings, ranging from "coarse" to "fine."

The ideal espresso water has the lowest alkalinity and hardness level. This can be achieved with a water filter system that bypasses all chlorine and adds back in a small amount of total dissolving solids (TDS) to add some calcium more info and magnesium to the mix. This will ensure the right balance between acidity and hardness and also avoid the necessity of decalcifying.
Using a high-quality filter water is essential to your machine's longevity health and the flavor of the coffee it produces.
